DB3J314K0L Equivalent & Substitute Parts

Part Overview

The DB3J314K0L is a Schottky diode manufactured by Panasonic Electronic Components, rated for 30 V DC reverse voltage and 30 mA average rectified current in a surface mount SMini3-F2-B package. This component is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and production needs. Substitute parts must maintain compatibility with the electrical specifications and physical mounting constraints of the original design.

Substitute Part Grouping Explanation

Substitution of the DB3J314K0L requires identification of Schottky diodes that satisfy the following critical electrical parameters: maximum DC reverse voltage rating of at least 30 V, average rectified current capacity of at least 30 mA, and small signal switching characteristics. The substitute part must be surface mount technology with compatible package dimensions and thermal performance suitable for the application environment.

The BAT854W,115 qualifies as a substitute based on the following parameter alignment:

Technology Match: Both components are Schottky diodes with small signal switching capability (≤ 200 mA Io classification)
Voltage Rating: BAT854W,115 rated at 40 V exceeds the 30 V requirement of DB3J314K0L
Current Capacity: BAT854W,115 rated at 200 mA exceeds the 30 mA requirement of DB3J314K0L
Mounting Type: Both are surface mount components
Compliance: Both components are RoHS compliant and MSL 1 (Unlimited)

Physical package differences exist between SC-85 (SMini3-F2-B) and SOT-323, requiring PCB layout verification during implementation.

Engineering Selection Recommendations

The BAT854W,115 is an active product from Nexperia USA Inc. with established supply chain availability, addressing the discontinuation status of the DB3J314K0L. Both components maintain RoHS compliance and MSL 1 moisture sensitivity classification, supporting equivalent environmental and regulatory requirements.

The BAT854W,115 provides electrical performance margins above the DB3J314K0L specifications across voltage rating (40 V vs. 30 V) and current capacity (200 mA vs. 30 mA). The higher maximum junction temperature rating (150°C vs. 125°C) offers thermal design flexibility.

Physical package transition from SC-85 (SMini3-F2-B) to SOT-323 requires PCB layout modification. Pin-to-pin compatibility must be verified against the specific application schematic and board design constraints prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the BAT854W,115 directly replace the DB3J314K0L without PCB modifications?

A: No. The DB3J314K0L uses SC-85 (SMini3-F2-B) package, while the BAT854W,115 uses SOT-323 package. Physical footprint differences require PCB layout changes. Pin configuration must be verified against application schematics.

Q: What are the key electrical differences between these parts?

A: The BAT854W,115 exceeds DB3J314K0L specifications in voltage rating (40 V vs. 30 V), current capacity (200 mA vs. 30 mA), and maximum junction temperature (150°C vs. 125°C). Both are Schottky diodes with small signal switching characteristics. Forward voltage and reverse leakage are specified at different measurement conditions and cannot be directly compared.

Q: Are both parts RoHS compliant?

A: Yes. The DB3J314K0L is RoHS Compliant. The BAT854W,115 is ROHS3 Compliant. Both meet RoHS requirements.

Q: What is the moisture sensitivity classification for these diodes?

A: Both the DB3J314K0L and BAT854W,115 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Why does the BAT854W,115 have higher capacitance than the DB3J314K0L?

A: Capacitance values are specified at different measurement conditions (1.5 pF @ 10 V for DB3J314K0L vs. 20 pF @ 1 V for BAT854W,115). Capacitance varies with applied voltage. Direct comparison requires measurement at identical bias conditions.

Q: Is the BAT854W,115 currently available in production quantities?

A: Yes. The BAT854W,115 is listed as Active product status with 85,162 pieces in stock, providing established supply availability compared to the discontinued DB3J314K0L.

Q: What package type is the BAT854W,115?

A: The BAT854W,115 uses SOT-323 package (also designated SC-70), a surface mount package different from the SC-85 (SMini3-F2-B) of the original part.
